Function Table 2 describes the functions of a 650 W DC PoE power module.
Function  | Description  | |
Input protection  | Input undervoltage protection  | In this protection state, the power module stops supplying power. When the input voltage restores to the normal range, the power module automatically resumes power supply.  | 
Input overcurrent protection  | In this protection state, the power module stops supplying power and cannot automatically resume power supply when the input current restores to the normal range.  | |
Output protection  | Output overvoltage protection  | In this protection state, the power module stops supplying power intermittently. When the system recovers from output overvoltage, the power module automatically resumes power supply.  | 
Output overcurrent protection  | In this protection state, the power module supplies power intermittently. When the output current is within a range, the power module automatically resumes power supply.  | |
Output short-circuit protection  | In this protection state, the power module supplies power intermittently. When the short circuit is removed, the power module automatically resumes power supply.  | |
Overtemperature protection  | When the temperature of the power module exceeds a specified threshold, the power module stops supplying power. When the temperature falls into the normal range, the power module automatically resumes power supply.  | |
Hot swap  | Supported  | |
NOTE: When a power module enters overtemperature protection state, take measures to lower the ambient temperature. The power module can automatically resume power supply when the temperature falls within the normal range.
